Personality & CharacteristicsEdit
Both as a human and Immortal, You Shikou maintains a rather playful and carefree nature unlike the other Immortals who mostly possess cold personality and contempt for humans. His carefree nature allows him to get along with other Immortals easily as seen where he often drinks with the Purple Immortal or plays pranks on him (trying to make him trip over) and lifts the White Immortal's mood when he is depressed at Eigetsu's loss.
In spite, of his carefree nature, he possesses a much ruthless side when he is angered. His ill temper is shown during Shuurei's attempt to pass through Fort Sairi where the people were rebelling against her. Due to the ungrateful nature of those humans, Dr. You's contempt for the humans like the others awaken once again. His ruthlessness is also seen after Hyou Ren's Jyasenkyou incident, where he murdured every member of the Hyou Clan, who attempted to capture SHuurei and EIgetsu on Ren's command.
